Efficacy and Safety of the Use of Memantine for Preserving Cognition in Adult Patients With Epilepsy

After a two-month prospective baseline during which seizure frequency and neurocognitive parameters are documented, patients will be randomized to either memantine or placebo and evaluated after twelve months on study drug. The treatment period will consist of a one month dose escalation phase, followed by an eleven month maintenance phase. The dose escalation is 5 mg in PM for days 1-7, 5 mg twice daily for days 8-14, 5 mg in AM and 10 mg in PM for days 15-21 and 10 mg twice daily from day 22 and continue.
